EE 2000 Logic Circuit Design, Semester A, 2007/08 Tutorial 3 The questions are divided into two levels. Level 1 is the basic level question. You should be able to answer them after completing the lecture. Level 2 is the advanced level question. You may have to take a research before answering them. Please be prepared before the tutorial. Level 1 Question 1: Can you tell the meaning of “1001” if it is a (a) Decimal number (b) Binary number (c) Octal number (d) Hexadecimal number (e) 4-bit 2’s complement number (f) BCD 8421 code (g) BCD 2421 code (h) Excess-3 code Question 2: To verify if the functions are equal by using truth table xy ’ + x z ’ + x y = ( x ’ + y ’)( x + y + z ’)? Question 3: Find the dual of the following Boolean function (a) xy ’ + x z ’ + x y = ( x ’ + y ’)( x + y + z ’) (b) prove the equivalence of the dual with truth table Question 4: Draw the logic circuit diagram of the Boolean function f ( x , y , z ) = ( x ’ + y ’)( x
